I would like to know, is there any service or method where only one ip adress can read data and other can't read.
no it is not possible to see others ip. cause it is prohibited...... if you are third party then you have all the rights and u can see.
You could set up a PHP script that detects if you have a particular IP then feeds you data, if that's what you're wondering.
No i don't want that. Suppose your ip address is 101.111.111.001 and i will give you permission to access from this Ip address than only you can, no body can access else you. For example - You have provide me your organisation Ip Address than only organisation can access else nobody. I can't use username and password to give particular organisation because third party also can see. IP address is best. I want that.
Yep. Don't know anything about PHP, but in .NET you just need to detect the connecting IP to that page and decide whether to show the page or show them something else. I imagine PHP will have the ability to do the same thing. Shouldn't be difficult for a programmer to implement for you. It's not fool-proof though and IP addresses can be spoofed. If the data was sensitive then you might want to look for a more robust password-protected system. If it's the whole server you want to do this for then a firewall will do it.
You can configure it using the .htaccess file. You will then be able to allow access to the IP's you want & deny all others.
What everyone is saying is correct and are methods that will work. It is you who don't seem to be understanding. These methods - whatever you use - will ALLOW a specific IP address to access the content of a specific page or folder and block all others from seeing it.
This is incorrect. You can use this configuration in .htaccess to accomplish this: Allow from IP.IP.IP.IP Allow from IP.IP.IP.IP/BITS Allow from IP.IP.IP.IP/NETMASK Deny from All This will allow the IPs listed, and deny all others.
just follow this method or just search in google for more detail explaination and method. you could atleast try it to see if it is what you are looking for?.
